1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundRhythmic masticatory muscle activity (RMMA) is a biomarker of sleep-related bruxism (SRB). Sleep quality and sympathetic nervous system activity are associated with SRB onset. We focused on fluctuations in blood glucose levels during sleep, which are considered to affect these factors.

objectivesThis study aimed to clarify the effects of stabilising blood glucose levels through dietary instructions on SRB improvement.

methodsNineteen healthy adults diagnosed with SRB were included in this study. The first 7 days were the non-intervention period, and the second 7 days were the dietary instruction period (prohibiting sugary beverages, alcohol consumption and high-carbohydrate snacks). A portable continuous glucose monitoring device, polysomnography, electromyography and pulse oximetry were used to measure and compare the interstitial fluid glucose concentration (which is highly correlated with blood glucose levels), electroencephalogram frequency analysis, RMMA frequency per hour (RMMA Index) and heart rate variability.

resultsAfter instruction, blood glucose fluctuations during sleep [standard deviation of glucose concentration in interstitial fluid (11.0 ± 5.5 to 5.7 ± 3.3 mg/dL, p < 0.01)] decreased significantly and RMMA Index (9.9 ± 3.7 to 7.0 ± 2.8 episodes/h, p < 0.001) also decreased significantly. Analysis of heart rate variability showed a decrease in sympathetic nervous activity, but there were no significant changes in sleep quality indicators based on electroencephalogram analysis.

conclusionStabilisation of blood glucose levels during sleep may improve SRB, particularly by suppressing sympathetic nervous system activity.
